MEANS FOR lNFLATlNG LlFEj-BELTS.

SPECIFICATION forming part of Letters Patent No. 752,654, dated February23, 1904. Application filed September 25, 1903. Serial No. 174,646. (Nomodel.)

To all whom it may concern.-

Be it known that we,HENRY OLEws,J r. gentleman, of 630 Fifth avenue, NewYork city, State of New York, and FREDERICK YOUNG DALZIEL, gentleman, of5 Avenue du Bois de Boulogne, Paris, France, have invented certain newImprovements in the Means for In- Hating Life or Safety Belts, of whichthe following is a full, clear, and exact description.

This invention relates to safety or life belts; and it consists inimproved means for inliating at will and instantaneously safety or lifebelts to be used in the water and composed of an air-tight chamber orchambers in rubber or similar material.

The invention consists in providing safety or life belts with areceptacle containing highly-compressed air,hermetically connected tothe belt by a tube, and a device allowing the instantaneous puncture ofthis receptacle in order to allow the air contained therein to escapeinto the belt through this tube and to inflate the air-tight chamber orchambers of the belt.

This invention will now be more fully described in reference to theaccompanying drawings, in which-fF Figure 1 shows the belt before theinflation. Fig. 2 is a corresponding view showing the same infiated.

In both figures the same letters of reference `denote the same parts.

A is the belt.

B shows the receptacle containing compressed air or other gaseous matteror fluid.

C is the tube.

D is the perforating device.

The receptacle B is contained in an outer cover or receptacle B', whichis screwed into the tube C. By screwing it inwardly, as shown in Fig. 2,the receptacle B is brought against the points D.

When it is intended to inflate the belt in case of danger, it is onlynecessary to turn the receptacle B', which Will cause the perforatingdevice D to puncture the bottom of the receptacle B and allow the aircontained therein to escape into the air-tight chamber or chambers ofthe belt through the tube C. The life-belt now becomes buoyant and isable to support the body in the water.

It is well understood that the shape and the size of the belt and outerreceptacle, as well as the material of which same are made, may varywithout in any way departing from the principle of this invention.

Having now particularly described our invention, we declare that what weclaim is- 1. A safety or life belt comprising an inflatable chamber, areceptacle B containing compressed iiuid, a cover for said receptacle, atube Cinto which the cover is screwed and points on the tube C againstwhich the receptacle B is forced by screwing in the outer cover,substantially as described.

2. In combination in a safety or life belt, a receptacle carrying acompressed uid, points against which the receptacle is forced to breakthe same and means for forcing the receptacle against the points,substantially as described.

3. In combination, an inflatable chamber, a tube O having an openingleading into said chamber, points D at the said opening, a receptaclefor compressed iuid and a cover carrying the said receptacle and movableinto the said tube, substantially as described.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
